Charge master here w/o problems. Over the years I broke 2 bullet pullers. They replaced them within 10 days. Also have a rcbs prep station. Just stopped working one day. RCBS said send it back and they'll replace it With in two weeks had another. RCBS customer service is some of the best I have encountered.
best automatic powder dispemser?

The Chargemaster IS slow. If I'm trying to make time, I'll seat the bullet while it's throwing the next charge. I don't use my manual powder dispensers for anything. I'm either in single stage persnickety mode with the Chargemaster, or moving fast with an auto-indexing turret press. All my pistol and blaster rifle stuff is done on the turret.

Here's a very informative comparison on the subject.
Test review of RCBS, Lyman, and PACT digital electronic powder measures for shooting and reloading. Dispenser speed, accuracy, price, warranty comparison testing. IMR 4064 and H4831 extruded stick powder kernels weighed. Balance beam Prometheus scale accuracy. 6mmBR.com is for 6mm BR Benchrest precision shooting with 6BR FAQ, Reloading Data, Message Boards. Bullets, ammo, gun, barrel, powder, primers, stocks, dies, accurizing, ballistics, tools, gunsmiths, gunsmithing, and varminting.
As far as the Chargemaster being slow, yes they are. But you can very easily improve their drop speeds, as I have, by following the instructions detailed here"
My drop times were quite literally reduced by half.If it's true that we are here to help others, then what exactly are the others here for?

I set mine to 44.2 and can actually see when it is going to be a heavy drop. It doesn't happen very often but if it reads 44.1 and drops more than 3 kernels of varget, it is going to be over.If it's true that we are here to help others, then what exactly are the others here for?

Klem - while I knew mine was pretty stable and accurate, I was quite surprised to read this. My scale always stays in the environment where it will be used, so that helps with temperature stabilization issues. No warm up time, to speak of, has ever been needed, either. I weigh the slugs and, if needed, recalibrate then. Not needed, very often, though.If it's true that we are here to help others, then what exactly are the others here for?

I can't settle for +/- .1 grain. My scale resolves to +/- .02 grains allegedly. In all actuality it is +/- .02-.04 grains. I think if I ever get a charge master, I would relegate its use to very weight tolerant loads like my .30-06, and .223 loads and .308 loads.
The 6.5's I have are precision machines and those charges get weighed to the +/- .02-.04 range.

For example, Chrony chronographs acknowledge a 5% potential error in their literature yet display velocities under 1,000fps to one decimal place. Is the 983.7 fps on the display really XXX.7fps?, unlikely.

Originally posted by Klem View PostRespectfully, I think there is a point beyond which precision in weighing is subsumed by other variables that contribute to the group size on a particular day. I will also say that just because a digital meter displays numbers implying a degree of precision to (for example) 0.01 there is no guarantee the machine is giving you that precision.

I fully understand that train of thought. However, don't you want to eliminate the most amount of variables possible?
Having highly accurate charges leads to extremely low ES/SD's. Keeping more good shots honest.

As far as the chrony goes, that is just to get a ball park # for ballistics software, so proving my real world numbers is easier to do.
Also which, with the results of the real world results I can true the ballistic software and come up with reliable numbers for intermediate ranges that I haven't proven and taken note of.

How much do the individual kernels of your powders weigh? If they are heavier than your 0.02gr standard then it's a lot of faffing around re-throwing in order to achieve this. And hopefully that precision makes a difference.
